Method and device for processing communication between network management equipment and mobile terminal

technical field

The present invention relates to a communication processing method and device in a wireless communication network, in particular to a method and device for processing communication between a network management device and a mobile terminal in a multi-carrier wireless communication network.

Background technique

In LTE subsequent evolution (LTE-Advanced, LTEA for short), carrier aggregation (Carrier Aggregation, CA) is selected as an important technology for improving system performance. LTEA defines three types of carrier components (Carrier Component), namely backward compatible carrier component, non-backward compatible carrier component and stand alone carrier component. Among them, LTE-based mobile terminals (hereinafter referred to as LTE terminals) can only access backward compatible carrier components, while LTEA-based mobile terminals (hereinafter referred to as LTEA terminals) can access backward compatible carrier components and non-backward compatible The carrier component, as for the stand alone carrier component, it cannot be accessed alone. In other words, an LTEA terminal can only access the stand alone carrier component after accessing the backward compatible carrier component and/or the non-backward compatible carrier component. .

In the LTE system, an LTE terminal only accesses one component carrier, and a network management device such as a base station assigns it a cell temporary identifier (C-RNTI) as the terminal identifier of the mobile terminal on the component carrier.

However, unlike the LTE system, the LTEA system is a multi-carrier system. As mentioned above, one LTEA terminal can access multiple carrier components. How to ensure the correct processing of information in such a multi-carrier system has become a very important issue, and it is obvious that the existing single-carrier solution in the LTE system cannot be applied here.

For this reason, a new solution for handling communication between a network management device and a mobile terminal is required.

According to one aspect of the present invention, a network management device is provided, which includes the above-mentioned first device.

According to one aspect of the present invention, a mobile terminal is provided, which includes the above-mentioned second device.

In order to help the understanding of the present invention, some concepts appearing in this paper are explained below:

Activation: A carrier is activated for a mobile terminal, which means that the mobile terminal is allocated radio resources on the carrier. Correspondingly, a carrier is no longer activated for a mobile terminal, which means that the network management device takes back the previous The radio resource on the carrier allocated to the mobile terminal, after that, the carrier is in a deactivated (deactivated) state relative to the mobile terminal.

Independent carrier and non-independent carrier: In this paper, the carrier in the carrier component that can be accessed independently is called an independent carrier, and the carrier in the carrier component that cannot be accessed independently is called a non-independent carrier. Those skilled in the art understand that, above, the independent carrier is not limited to the carrier in the backward compatible carrier component and the non-backward compatible carrier component, and the non-independent carrier is not limited to the carrier in the stand alone carrier component. Taking the LTEA system as an example, the entire wireless frequency band may include multiple carriers, and one or more of these carriers belong to independent carriers, while the other one or more carriers belong to non-independent carriers. The idea of the present invention is not affected by specific carrier division methods. In the present invention, a typical example of a non-independent carrier is a stand alone carrier component that does not carry control signaling itself.

The first quantity and the second quantity: the value of the above first quantity may be an integer greater than or equal to 1.

Terminal ID: In order to perform uplink or downlink communication, a mobile terminal needs to be assigned a terminal ID. In this way, according to the resource allocation information indicated by the terminal ID, the mobile terminal will know what wireless resources should be used, such as specific frequencies and time slots Or pseudocode, etc. to communicate with the network management device. In order to effectively distinguish the information of different terminals in the uplink and downlink information, different mobile terminals should be assigned different terminal identities on the same carrier. Without conflict, the terminal identifier of the mobile terminal can be reused between different carriers.

Network management equipment: Refers to various network equipment such as base stations, which are used to communicate with mobile terminals and undertake management functions. As the field of wireless communication develops, its nomenclature and implementation may change, but the network management device in this article should be understood to cover various reasonable changes.

Processing of information: In this paper, processing of information includes but is not limited to the following items: encoding and decoding of signaling or data; other physical layer processing of signaling or data.

Multi-carrier system: The multi-carrier system described herein refers to a system divided into multiple carriers, even if only one of the carriers is actually used at the current moment.

The above and other concepts and definitions will become clearer and easier to understand by reading the more detailed descriptions that follow in this text.

In the present invention, by distributing terminal identifiers in a multi-carrier system and providing a solution for non-independent carriers, the support for information processing in multi-carriers is effectively realized. In addition, since the terminal identity corresponding to one carrier assigned to a mobile terminal can be used as the terminal identity corresponding to another carrier of the mobile terminal or another mobile terminal, the number of supported terminals increases significantly.

Detailed ways

A typical application scenario of the present invention is shown in FIG. 1 , a base station 1 governs multiple mobile terminals in a cell, and only mobile terminals 21-23 are shown in the figure for simplicity. The network shown in Figure 1 specifically works in a multi-carrier environment, without loss of generality, four carriers are defined as shown in Figure 2, where carrier A is located between frequencies f1 and f2, and carrier B is located between frequencies f2 and f3 Carrier C is located between frequencies f3 and f4, and carrier D is located between frequencies f4 and f5. The number of carriers in FIG. 2 should not be construed as limiting the protection scope of the present invention. In the actual application of the present invention, one base station may have more or fewer carriers, such as three. Importantly, the division of carriers existing in the prior art can be easily applied to the present invention.

Without loss of generality, the base station 1 and the mobile terminals 21-23 in this example belong to the LTEA system. Further, it is defined that the carriers A and B in FIG. 2 belong to the backward compatible carrier component, and the carrier C belongs to the non-backward compatible component. The carrier D belongs to the stand alone carrier component. Therefore, in this example, carriers A, B, and C are independent carriers, which are also referred to as independent carriers A, B, and C hereinafter, and carrier D is a non-independent carrier, and is also referred to as non-independent carrier D hereinafter.

After understanding the applicable scenarios of the present invention, the method provided by the present invention will be described in detail in conjunction with the flow chart. Fig. 3a shows a flowchart of a system method for processing communication between a network management device and a mobile terminal in a multi-carrier system according to a specific embodiment of the present invention, wherein, refer to Figs. 1 and 2 and mainly use the base station therein 1 and mobile terminal 21 as an example.

The process shown in Fig. 3a starts from step S11, wherein, in a random access (random access) process, the base station 1 activates a first number of independent carriers for the mobile terminal 21. Here, the number of activated independent carriers depends on the resource requirements of the mobile terminal 21 and the division method of carriers. According to a specific embodiment of the present invention, the base station 1 may first activate a carrier A for the mobile terminal 21, and then activate another carrier, such as carrier B, for the mobile terminal 21 when the carrier A cannot meet the service requirements of the mobile terminal 21.

As a result, in this example, the independent carrier A is activated for the mobile terminal 21 in step S11.

Therefore, in step S12, the mobile terminal 21 is assigned a terminal identifier corresponding to each independent carrier, as shown in Table 1, for the convenience of comparison, the terminal identifier allocation situation of another mobile terminal 23 is also shown in Table 1:

Table 1: Terminal ID allocation of mobile terminals

It is not difficult to see from Table 1 that base station 1 assigns different terminal identities corresponding to the same independent carrier to different mobile terminals. However, for the same mobile terminal, the terminal identifiers corresponding to different independent carriers assigned by the base station 1 may be the same or different. In addition, if an independent carrier is no longer activated for a certain mobile terminal, the mobile terminal 23 will release the corresponding terminal identification, and this identification can be assigned to other mobile terminals as the terminal identification corresponding to the independent carrier without conflict.

Although step S11 and step S12 are shown as being performed sequentially in FIG. 3a, those skilled in the art understand that after activating an independent carrier, the corresponding terminal identifier can be allocated immediately, and then the next independent carrier is activated and the corresponding terminal is allocated. logo.

For an LTE terminal such as the mobile terminal 22 shown in FIG. 1, when multiple independent carriers such as carriers A and B are activated for it, the base station 1 assigns a terminal identification to the mobile terminal 22, wherein the terminal identification corresponding to carrier A The terminal identifier corresponding to carrier B may be the same or different.

On the side of the mobile terminal 21, it correspondingly receives each terminal ID sent by the base station 1. Specifically, the terminal ID allocation process shown in FIG.

After the mobile terminal 21 obtains the terminal identifier 0001 corresponding to the independent carrier A, it can use this identifier to decode all the information sent by the base station 1 on the independent carrier A and perform a series of physical layer processing, and can use this A series of physical layer processing such as encoding all information to be sent to the base station on the independent carrier A by using the identifier. The above information includes signaling and data on PDCCH and PDSCH.

Thereafter, the traffic volume of the mobile terminal 21 increases, and it may be difficult to deal with it only with the independent carrier A, resulting in information blockage and unfavorable situations such as packet loss. Therefore, the base station 1 preferably further activates other than the independent carrier A for the mobile terminal 21. other carriers. Among them: Different standards may have different selections for other carriers. For example, the activation order of increasing frequency may be used, or the activation method of random selection may be used. In addition, for the use of non-independent carriers, it may be used when independent carriers have been exhausted. Use is not limited to this.

In this example, without loss of generality, the activation sequence of increasing frequency is adopted. Since the service demand of the mobile terminal 21 continues to increase, the independent carriers B and C with frequencies higher than the independent carrier A are also activated for the mobile terminal 21 one after another. Here, the base station 1 has assigned a corresponding terminal ID, and based on the assumption that the terminal ID allocation result of the mobile terminal 23 has not changed, the new terminal ID allocation is shown in Table 2:

Table 2: Terminal ID allocation of mobile terminals

Table 2 further proves that in the present invention, the terminal identifiers corresponding to different carriers assigned to the same mobile terminal can be the same or different.

In this example, the base station 1 uses RRC signaling to send the terminal identifiers 0001 and 0010 corresponding to the independent carriers B and C. After receiving these two identifiers, the mobile terminal 21 uses them for the mobile terminal on the corresponding independent carrier. Processing of information, the above information includes signaling and data on PDCCH and PDSCH.

Step S13 is a judging step, and the triggering conditions of this step are different due to different specific implementations. For example, when the carrier trigger sequence is increasing in frequency, since the non-independent carrier D in Fig. 2 has the highest frequency without any limitation, it is possible to activate it only after all independent carriers have been activated for the mobile terminal 21 , therefore, the judgment in step S13 can be triggered after all independent carriers have been activated,

Thereby, it is beneficial to save the hardware resources at the base station 1; differently, if the carrier trigger sequence is random or other causes the trigger opportunity of the non-independent carrier D to be the same as that of the independent carrier, step S13 is executed periodically after step S11, when When conditions are not met,

Wait for a while or judge again immediately.

Regardless of the triggering sequence, when the base station 1 triggers the second number of non-independent carriers for the mobile terminal 21, the base station 1 will allocate terminal identities corresponding to these non-independent carriers to the mobile terminal 21 in step S14. In this example, the value of the second number is 1. Those skilled in the art understand that if the number of non-independent carriers is different from that shown in FIG. 2, for example, there are as many as three, the value of the second number here can reach 3.

Therefore, after step S14, the distribution result of the terminal identifier is shown in Table 3, wherein, assuming that the traffic demand of the mobile terminal 23 also increases, the base station 1 also activates the non-independent carrier D for it:

Table 3: Terminal ID allocation of mobile terminals

It can be seen from Table 3 that, similar to the independent carrier, the terminal identities assigned to different mobile terminals corresponding to the same non-independent carrier are preferably different from each other. For the same mobile terminal, base station 1 allocates the same terminal identifiers corresponding to independent carriers A, B and non-independent carrier D, thereby saving resources such as terminal identifiers. Of course, those skilled in the art understand that if the resource of the terminal identifier is not in short supply, the terminal identifiers corresponding to different carriers allocated to the mobile terminal 21 may also be different from each other.

After receiving the terminal identifier 0001 corresponding to the non-independent carrier D, the mobile terminal 21 can use the identifier to process information on the non-independent carrier D, such as encoding, decoding and other physical layer operations. Taking the LTEA system as an example, the mobile terminal 21 first uses the terminal identifier corresponding to the independent carrier transmitting the PDCCH, such as independent carrier A, to decode the PDCCH, thereby finding the radio resource for transmitting the PDSCH, and then, the mobile terminal 21 uses the radio resource for transmitting the PDSCH The terminal identifier corresponding to the carrier where it is located is used to decode the PDSCH.

Step S15 is another judging process, wherein the base station 1 judges whether there is at least one independent carrier or non-independent carrier that is no longer active for the mobile terminal 21 among the independent carriers and non-independent carriers that are activated for the mobile terminal 21. active state. The reason for this situation is often that the traffic volume of the mobile terminal 21 drops, or the mobile terminal 21 is turned off, and so on. Wherein, on the basis shown in Table 3, the order of deactivating the activated carriers according to the decrease in the traffic volume of the mobile terminal 21 can be decremented according to the frequency, or can be randomly determined, etc., and the present invention is not limited by its impact in specific ways. Those skilled in the art should understand that considering the existence of a non-independent carrier, since it cannot be independently accessed, it is preferably deactivated first, or considering its existence and always ensuring that there is at least one independent carrier in an activated state .

In this example, without loss of generality, the non-independent carrier 21 is to be deactivated for the mobile terminal 21, so in step S16, the base station 1 notifies the mobile terminal to release the assigned terminal identifier 0001 corresponding to the non-independent carrier D , the notification process may use RRC signaling. Thereafter, the terminal identity 0001 can be allocated to other mobile terminals for the non-independent carrier D without interference/confusion. Of course, if it is not used by other mobile terminals for the non-independent carrier D, and mobile terminal 21 has a significant increase in traffic at a certain moment thereafter, then 0001 can be allocated to it again, and if 0001 has been used by another mobile terminal at this time If a mobile terminal is used for the non-independent carrier D, other terminal identifiers may be allocated to the mobile terminal 21, which will not be described in detail.

Those skilled in the art understand that although steps S15 and S16 are shown after steps S13 and S14 in FIG. , after step S12, or even after step S11, step S15 can be executed. In different stages, the carriers considered in step S15 are different, because the carriers activated for the mobile terminal 21 in different stages are different.

In the embodiment described above in conjunction with FIG. 3 a , after activating the second number of non-independent channels for the mobile terminal 21 , the base station 1 assigns the mobile terminal 21 terminal identities corresponding to these non-independent channels. An alternative example of this embodiment will be introduced below.

In FIG. 3b, the same or similar parts as in FIG. 3a have been denoted by the same reference numerals as those in FIG. 3a, and will not be described again. The following discussion will focus on step S17 which is different from that in FIG. 3 a . It should be understood that the size of the reference numerals herein does not necessarily indicate a strict sequence between the steps, which has already been reflected in the context.

In this example, for the non-independent carrier D activated for the mobile terminal 21, the base station 1 does not specifically assign a terminal identifier corresponding to the non-independent carrier D to the mobile terminal 21 as in step S14 in FIG. 3a. Instead, the base station 11 and the mobile terminal 21 perform information processing of the mobile terminal 21 on the non-independent carrier D based on the previously allocated terminal identifier corresponding to the independent channel.

For each non-independent carrier activated for the mobile terminal 21, it becomes a problem to be solved to use the terminal identifier corresponding to which independent carrier is allocated for the mobile terminal 21. Typically, the terminal identifier used for processing the information of the mobile terminal 21 on the non-independent carrier D corresponds to the independent carrier used when the base station 1 sends the control signaling corresponding to the non-independent carrier D to the mobile terminal 21 . More typically, the terminal identifier used for processing the information of the mobile terminal 21 on the non-independent carrier D corresponds to the independent carrier used when the base station 1 sends resource allocation information corresponding to the non-independent carrier D to the mobile terminal 21 . Specifically, working under the solution shown in FIG. 3b, the mobile terminal 21 has been pre-set so that it can smoothly cooperate with the base station 1 to execute the process shown in FIG. 3b. In step S17, when the mobile terminal 21 uses When decoding the PDCCH with a terminal identity corresponding to an independent carrier such as independent carrier A, it finds resource allocation on the non-independent carrier D, so the mobile terminal 21 uses the terminal identity corresponding to the independent carrier A to register the non-independent carrier D Decode the PDSCH on it.

The following will introduce the device corresponding to the above method provided by the present invention in conjunction with the block diagram. Since the features of the modules/device correspond to the steps in the above method, they will be simplified.
