Problems solved by technology

However, with the continuous deepening of IP, the wireless access system and the core network can achieve full IP intercommunication, and the pool can be configured to be large to achieve more resource sharing. At this time, the current routing method can no longer meet the needs.

[0045] Such as figure 2 As shown, this embodiment is the process when the mobile terminal registers in the network for the first time. This embodiment is applied to System Architecture Evolution (SAE), and compare figure 1 , figure 2 MME (MobilityManagement Entity, mobility management entity) corresponds to figure 1 Core network service node in the eNB, corresponding to eNB (evolved node B) figure 1 The radio access network unit in the UE (User Equipment) corresponds to figure 1 Mobile terminal in.

[0046] The registration process includes the following steps:

[0047] Step 201, the UE attach request message is transmitted through the initial direct transfer message of the RRC (Radio Resource Control) message between the UE and the eNB, and the initial direct transfer message includes the attach request message (non-access stratum message) between the UE and the MME And the identification information of the UE when it registered last time, the identification information inc...

[0077] Such as image 3 As shown, this embodiment is a process when a mobile terminal is kept within the range of a radio access network managed by the same MME pool and activates a certain service in an idle state. In this process, the UE has saved a valid MME ID and Pool ID before initiating a service request. The steps are as follows:

[0078] In step 301, the service request message of the UE is transmitted through the initial direct transfer message of the RRC message between the UE and the eNB, and the initial direct transfer message includes the service request message (non-access stratum message) and the identification information of the UE at the last registration. The identification information includes MME ID, Pool ID and PLMNID;

[0079] The identification information is carried in the initial direct transmission message so that the eNB does not need to parse the non-access stratum message (in this case, the service request) when it finds the way.

[0084] Such as Figure 4 As shown, this embodiment is a tracking area update procedure when a mobile terminal moves to the range of a radio access network managed by another MME pool in an idle state. In this process, the Pool ID saved in the UE is not the ID of the MME pool currently to be accessed, therefore, the Pool ID and MME ID saved in the UE are invalid. The steps are as follows:

[0085] Step 401: When the UE detects that the tracking area has changed (the tracking area list broadcast by the cell has no intersection with the tracking area list saved by the UE), it sends a tracking area update request message. The tracking area update request message of the UE passes between the UE and the eNB The initial direct transmission message of the RRC message includes the tracking area update request message (non-access stratum message) and the identification information of the UE at the last registration. The identification information includes: MME ID, Pool ID and PLMN ID;

Abstract

The invention discloses a routing method in the wireless network, and the method can meet the full IP intercommunication need of a wireless access system and a core network without limiting the managed user number any more. The method includes the following steps: (a) a mobile terminal sends out non-access layer information and identification information of the last time registration to a wireless access network unit, the identification information includes MME ID, Pool ID and PLMN ID; (b) if the PLMN ID is effective, a domain for the core network service node pool of the terminal connection, which is corresponding with the PLMN, is produced according to the PLMN ID, a resource manager which is corresponding with the core network service node pool is accessed according to the domain, and a core network service node for the terminal is distributed by the resource manager, so as to send out the non-access layer information to the core network service node; (c) the core network service node can register to a home subscriber server and feedback the current MME ID and the Pool ID to the mobile terminal; (d) the mobile terminal carries out the storage.

Description

Technical field [0001] The invention relates to a wireless network, in particular to a routing method in the wireless network. Background technique [0002] The WCDMA version 5 (hereinafter referred to as R5) released by 3GPP describes a method for core network nodes to jointly manage a group of radio network controllers (RNC), which is the concept of a so-called "pool". A core network node pool is defined as: an MS (Mobile Station) roams without changing the area of ​​the core network service node (Serving CN Node); a pool is served by one or more core network service nodes; RNC managed All cells belong to the same pool. [0003] In R5, NRI (Network Resource Identifier) ​​is used to identify different core network service nodes. When a mobile terminal registers in a certain pool for the first time, the RNC allocates a core network service node to it according to the load sharing principle, and sends the registration request message of the mobile terminal to the core network serv...
