Description
Technical Field
The present invention relates to the field of communications, and in particular, to a paging processing method and apparatus.
Background
The third generation partnership project (3rd generation partnership project, abbreviated as 3GPP) is a System Architecture Evolution (SAE) project for next generation mobile radio networks. The architecture of SAE is shown in fig. 1, which includes the following network elements:
evolved radio access network (evolved RAN, abbreviated E-RAN): higher uplink and downlink rates, lower transmission delays and more reliable wireless transmissions may be provided. The network element included in the E-RAN is enodeb (evolved node b), and provides radio resources for the terminal to access.
Home subscriber server (homesubscriber server, HSS for short): the user subscription data is permanently stored.
Mobility Management Entity (MME): a control plane functional entity, a server for temporarily storing user data, and a control plane functional entity, which is responsible for managing and storing a user equipment (user equipment, UE) context (such as UE/user identifier, mobility management status, user security parameters, etc.), allocating a temporary identifier to a user, and being responsible for authenticating the user when the UE is camped in the tracking area or the network; processing all non-access stratum messages between the MME and the UE; paging at SAE is triggered.
A serving general packet radio service support node (SGSN), a General Packet Radio Service (GPRS) supporting Gb or Iu access, a server for temporarily storing user data, and a server for managing and storing GMM context and PDP context; all non-access stratum messages between the SGSN and the UE are processed.
Serving gateway (ServingGateway, abbreviated as ServingGW or SGW): the gateway is a user plane entity, and is responsible for user plane data routing processing and terminating downlink data of the UE in an idle state. And managing and storing SAE bearer (bearer) context of the UE, such as IP bearer service parameters, network internal routing information and the like. Is an anchor point of the user plane in the 3GPP system, and one user can only have one ServingGW at one time.
A packet data network gateway (PDN gw), which is responsible for a gateway for accessing a PDN to a UE, allocates a user IP address, and is a mobility anchor point for 3GPP and non-3 GPP access systems. A user can access multiple PDNGWs at the same time.
Policy and aggregate charging rules function (policy and charging rules function, PCRF for short): the functional entity mainly generates a quality of service (Qos) rule and a charging rule for controlling user data transmission according to the service information, the user subscription information and the configuration information of the operator. The functional entity may also control the establishment and release of bearers in the access network.
The user is attached to the packet domain evolution network, the MME is restarted, the servingGW receives downlink service (including data or signaling), the implementation is realized according to the current 3GPP standard, the servingGW sends downlink data arrival information to the MME which is restarted and recovered, the MME carries International Mobile Subscriber Identity (IMSI), the MME sends paging information to the wireless access network element according to the IMSI to page the user, and the user is attached to the network again.
According to the current 3GPP standard, when an MME pages a user using an IMSI, the user is paged according to a tracking area identity list (taiilist). If there is no TAIlist, paging is performed in a tracking area (tracking area, TA for short) served by the core network, i.e., full-network paging.
However, when the MME is restarted and the ServingGW sends a downlink data arrival message, taiiiist is not carried, which results in that the core network needs to page in the whole network, and further results in a large invalid paging range, a waste of radio resources, a prolonged paging time, and an influence on the use experience of the terminal user.
According to the VoLTE (VoiceoverLTE) disaster tolerance specification issued by the current China Mobile, for MME restart, the solution that a serving GW receives downlink data is that 2 or more than 2 MMEs are required to form an MMEpool, and information such as IMSI and TAIList of an online user is mutually backed up between the MMEpools, after the MME accessed by the user is restarted, when the user needs to be called, the serving GW receives the downlink data of the user, the serving GW selects a normal MME in the MMEpool to which the restart MME belongs to send downlink data arrival information to carry the IMSI, and the normal MME finds backup information such as the IMSI and the TAIList of the user according to the IMSI and pages the user according to the IMSI and the TAIList.
However, although the core network of the VoLTE disaster recovery specification of the china mobile may page the user according to taiilist, the premise is that the MME between the mmepools needs to backup taiilist information, so that if the user data is not successfully backed up in time, the MME cannot obtain taiilist information for paging, and in addition, the requirement on the performance of the MME is high, the processing is complex, and actual deployment is difficult to a certain extent.
Aiming at the problems that in the related art, the MME cannot acquire the TAIlist information for paging, so that the invalid paging range is large, the wireless resources are wasted, and the paging time is prolonged, an effective solution is not provided.
