Embodiment approach 1

[0082] Figure 5 Embodiment 1 of the present invention specifically includes the following steps:

[0083] Step 501 , terminal 1 reports a measurement report, reporting information such as network element identifiers and signal strengths on the adjacent wireless side.

[0084] Step 502, the wireless side network element 1 attached to the terminal 1 finds that it is no longer suitable to serve it according to the measurement report reported by the terminal 1, and then selects a target wireless side network element with a strong signal to initiate a handover. If the wireless side network element 1 has started the local intercommunication function of the terminal 1, it needs to determine whether the terminal 1 can continue to maintain local intercommunication on the target wireless side network element.

[0085] Specifically, the wireless side network element 1 may compare whether the location of the target wireless side network element 1 is similar to the geographic location of...

Embodiment approach 2

[0102] Figure 6 The second embodiment of the present invention specifically includes the following steps:

[0103] In step 601, terminal 1 reports a measurement report, reporting information such as network element identifiers and signal strengths on the adjacent wireless side.

[0104] In step 602, the wireless side network element 1 attached to the terminal 1 finds that it is no longer suitable to serve it according to the measurement report reported by the terminal 1, and then selects a target wireless side network element with a strong signal to initiate a handover. If the wireless side network element 1 has started the local intercommunication function of the terminal 1, it needs to determine whether the terminal 1 can continue to maintain local intercommunication on the target wireless side network element.

[0105] Specifically, the wireless side network element 1 may compare whether the location of the target wireless side network element 1 is similar to the geograph...

Embodiment approach 3

[0125] Figure 7 The third embodiment of the present invention specifically includes the following steps:

[0126] exist Figure 6 In , the control plane network elements serving terminal 1 are the same, and in practical applications, there are cases where the control plane network elements serving terminal 1 are different after handover, and the invention points of the present invention are still applicable in this scenario. The difference is that the local intercommunication information needs to be carried in the message (such as forwarding the relocation request) between the two control plane network elements, as described in steps 703-708. Other steps with Figure 6 The same, will not be repeated here.

[0127] In the above embodiments 1, 2, and 3, if the network element on the wireless side decides to release the routing optimization channel for local intercommunication, then the anchor gateway needs to know this, because the anchor gateway saves the local intercommuni...

Abstract

Embodiments of the present invention provide an implementation method and a network element device for local intercommunication. The terminal using local intercommunication under source wireless said network element needs to switching to destination wireless said network element, said source wireless network element notifies local intercommunication information to said destination wireless said network element when determining said terminal can manage local intercommunication on said destination wireless said network element; said destination wireless said network element establishes local intercommunication optimized route with the wireless said network element of said terminal's local intercommunication opposite part on the basis of said local intercommunication information. The technical solution of present invention can solve the problem of unreasonable treatment for intercommunication channel under the condition of local intercommunication when a terminal's handover occurs, guarantee the smooth establishment of local intercommunication and the timely release of the local intercommunication channel, and save network signaling, effectively avoid operation delay of the local intercommunication implementation.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for realizing local intercommunication and network element equipment when a terminal is handed over in a 3GPP network. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and at the same time reduce the operating costs of operators, the third-generation partner The 3rd Generation Partnership Project (referred to as 3GPP) standard working group is working on the research of the evolved packet system (Evolved Packet System, referred to as EPS). figure 1 A schematic diagram showing the structure of an evolved packet domain system, such as figure 1 As shown, the entire EPS system is divided into two parts, the wireless access network and the core network. The core network incl...
